More specifically, the retractable step 30 can be fixedly attached to a chassis (not shown) of the vehicle body structure 12, to elements of the floor 20 of the cargo area structure 16, or to the bumper 28. The retractable step 30 is movable from a retracted orientation shown in FIG. 1 to an extended orientation shown in FIG. 2. In the retracted orientation, the step 30 is partially concealed below the floor 20, the bumper 28 and the first side wall 22. In the extended orientation, the step 30 extends rearward and outboard away from the bumper 28 and relative to the cargo area 18. The retractable step 30 can include a telescoping structure, a pivoting structure, an articulated arm structure or a track and sliding step support structure (not shown) that enables the step 30 to move to and from the extended orientation (FIG. 2) underneath a rear corner of the bumper 28 and the retracted orientation (FIG. 1) in which the step 30 extends rearward from and laterally outboard of the rear corner of the bumper 28. Retractable steps, such as the step 30, are conventional structures. Consequently, further description is omitted for the sake of brevity.

Further, it should be understood from the drawings and the description hereinbelow, that the retractable step 30 can include any of a variety of designs and structures, such as a retractable step attached to or attachable to the first side wall 22 and/or the tailgate 26.

The first side wall 22 and the second side wall 24 are symmetrically constructed (mirror images of one another) but are otherwise structurally identical. Only the first side wall 22 will be described below for the sake of brevity. However, it should be understood from the drawings and the description herein that the description of the first side wall 22 applies equally to the second side wall 24.

The first side wall 22 includes an outer panel 40 shown in FIGS. 1 and 2, an inner panel 42, a support pillar 44 and an upper panel portion 46 that are shown in FIG. 3. The outer panel 40 is contoured in accordance with an overall exterior design of the cargo area structure 16 and can have any of a variety of contours and/or shapes, or can have a simple flat or near flat shape. The inner panel 42 can also be contoured and shaped in accordance the cargo area structure 16 design. However, in the depicted embodiment, the inner panel 42 is generally flat and planar extending perpendicularly upward from the floor 20, except in the area of the wheel well.

The upper panel 46 is horizontally oriented and extends in a vehicle lateral inboard direction from an upper end of the outer panel 40. As shown in FIGS. 10, 11 and 12, the upper panel 46 overhangs an upper end of the inner panel 42. The upper panel 46 further defines an upper surface 46 a of the first side wall 22.

Each of the first side wall 22 and the second side wall 24 includes a utility track 48. As shown in FIGS. 3-5 and 10-12, the utility track 48 is fixedly attached to the first side wall 22 immediately below the overhang of the upper panel 46. In other words, the upper panel 46 extends inboard over the utility track 48.

The utility track 48 is configured to receive and support cargo area accessories such as those disclosed in commonly assigned U.S. Pat. Nos. 9,623,787, 8,550,757, 8,408,853, 8,052,019 and 7,594,787, which are all incorporated herein by reference in their entirety. The utility track 48 is rigidly and fixedly attached to the first side wall 22 at a location below and adjacent to the upper surface 46 a of the upper panel portion 46 of the first side wall 22.

The utility track 48 is fastened to the inner panel 42 of the first side wall 22 via a plurality of pairs of fasteners F₁, as shown in FIG. 4. Only one pair of fasteners F₁ is shown in FIG. 4. The depicted pair of fasteners F₁ are vertically aligned and spaced apart from one another.

The utility track 48 is an elongated member shown in cross-section in FIGS. 10, 11 and 12. The utility track 48 has a generally U-shaped configuration when viewed in cross-section. The U-shape of the utility track 48 defines an elongated hollow channel 50 (hereinafter referred to as the channel 50) surrounded on three sides by parallel walls 52 and base wall 54. Outer ends of the walls 52 are each formed with projections 56 that extend back into the channel 50. The ends of the projections 56 extend into the channel 50 but are spaced apart from the walls 52 and the base wall 54. An elongated opening 58 (a horizontally oriented gap) is defined between the projections 56 is open to the channel 50. Further, the rear end of the utility track 48 is open. The inboard vertical portions of the parallel walls 52 define an upright surface 48 a. In other words, since the utility track 48 is fixed to the first side wall 22, the utility track 48 defines the upright surface 48 a of the first side wall 22.

A description is now provided of the handle assembly 14 in accordance with a first embodiment with specific reference to FIGS. 3-12. The handle assembly 14 basically includes a base 60, a grip handle 62 and an attachment assembly 64.

The base 60 includes an attachment portion 66, a contoured portion 68 and a handle supporting portion 70. The attachment portion 66 is has an outboard surface 66 a and an inboard surface 66 b (relative to the vehicle 10 when installed to the first side wall 22). The outboard surface 66 a includes a projection 66 c. The projection 66 c is an elongated flange that extends in an outboard direction perpendicular to the outboard surface 66 a. The projection 66 c is dimensioned and shaped to engage a surface of the attachment assembly 64 such that the projection 66 c prevents pivoting of the base 60 relative to the attachment assembly 64, as described in greater detail below. Alternatively, the projection 66 c can be inclined relative to the outboard surface 66 a in order to mate with the surface of the attachment assembly 64, as described below.

The contoured portion 68 extends away from the attachment portion 66 such that the handle supporting portion 70 is located above and inboard of the attachment portion 66. The handle supporting portion 70 extends upward and away from the contoured portion 68 with the grip handle 62 being rigidly and fixedly attached to the handle supporting portion 70.

When installed to the utility track 48, the attachment portion 66 overlays the projections 56 of the utility track 48. More specifically, the outboard surface 66 a of the attachment portion 66 of the base 60 overlays a portion of the upright surface 48 a of the utility track 48.

The grip handle 38 is an elongated bar shaped member that can have a rectangular cross-section, or, can have a cylindrical shape. The grip handle 38 is fixedly attached the handle supporting portion 70 via, for example, mechanical fasteners or welding techniques. Further, the grip handle 38 extends in a rearward direction from the base 60, with the handle assembly 14 installed to the first side wall 22. With the base 60 attached to the upright surface 48 a of the first side wall 22 and the overall shape of the base 60 is such that the grip handle 62 is positioned adjacent to and spaced apart from an upper surface 46 a of the first side wall 22 within the cargo area 18, above the floor 20 and above the step 30. Consequently, an individual using the step 30 to enter the cargo area 18 grabs the grip handle 38 to assist in stepping up into the cargo area 18.

As shown in FIGS. 3, 10-12, the contoured portion 68 extends in an outboard direction from the attachment portion 66 of the base 60 of the handle assembly 14. Consequently, the attachment assembly 64 is at least partially concealed by the contoured portion 68 when viewed from a rear portion of the vehicle 10, as shown in FIGS. 3, 10-12.

The attachment assembly 64 is basically a clamping device that attaches to the attachment portion 66 of the handle assembly 14 and clamps to the utility track 48. As shown in FIGS. 11 and 12, the attachment assembly 64 includes a clamping member 72, a clamping block 74 and a threaded fastener 76. The clamping member 72 is a generally flat metallic member. The clamping member 72 basically includes a central threaded aperture 72 a and a pair of grooves 72 b formed on one surface thereof along opposite sides of the threaded aperture 72 a. The grooves 76 are parallel to one another and are spaced apart from one another corresponding to the distance between the projections 56 of the utility track 48.

As shown in FIGS. 11-12, the threaded fastener 76 is inserted through an aperture 66 d defined by the attachment portion 66 of the base 60 of the handle assembly 14. The fastener 76 is further inserted through a bore 74 a of the clamping block 74, thereafter threadedly engaged with the central threaded aperture 72 a of the clamping member 72. As shown in FIG. 12, the clamping member 72 is inserted or slid into the channel 50 via the open end of the utility track 48. Thereafter the fastener 76 is tightened pulling the clamping member 72 closer to the clamping block 74 and the base 60. The projections 56 are located between the clamping member 72 and the clamping block 74 such that the clamping member 72 and the clamping block 74 clamp to the projections 56, locking the attachment assembly 64 and the handle assembly 14 in position to the utility track 48. Further, the projections 56 are retained with respective ones of the grooves 74 of the attachment assembly 64. As well, an anti-rotation block 74 b extending from (and formed unitarily with) the clamping block 74 prevents the attachment assembly 64 has pivoting or rotating relative to the utility track 48. The anti-rotation block 74 b has a square-shape dimensioned to snuggly fit into the elongated opening 58 of the utility track 48. Therefore, once the threaded fastener 76 is tightened clamping the attachment assembly 64 to the utility track 48, the anti-rotation block 74 b is forced into the elongated opening 58. As shown in FIGS. 7, 8 and 9, the projection 66 c formed on the attachment portion 66 of the base 60 contacts a surface of the clamping block 74 thereby preventing rotation or pivoting movement of the base 60 and the grip handle 62 relative to the attachment assembly 64 and the utility track 48.

Once installed to the utility track 48, the grip handle 62 of the handle assembly 14 extends in a direction parallel to the first side wall 22, as shown in FIGS. 10 and 12. Further, once installed to the utility track 48, the grip handle 62 of the handle assembly 14 is positioned such that with the tailgate 26 in the open orientation, an individual using the step 30 to enter the cargo area 18 grabs the grip handle 62 for assistance in stepping up into the cargo area 18 and/or stepping on to the tailgate 26.

The threaded fastener 76 has a hexagonal shaped head such that the threaded fastener 76 can be tightened or loosened using a conventional wrench. However, the hexagonal head can be replaced with a hand operated knob (not shown) such that a vehicle operator can install and remove the handle assembly 14 without the use of tools.

The handle assembly 14 is depicted in the drawings as being installed to a rear end of the utility track 48. It should be understood from the drawings and the description herein, that the handle assembly 14 can be installed to any of a variety of positions along the length of the utility track 48. Further, with the handle assembly 14 installed at the rear end of the utility track 48, other accessories (not shown) are retained for restricted movement along the length of the utility track 48 since the handle assembly 14 serves as an end stop for the utility track 48, preventing other accessories from being loosened and slid out the open end of the utility track 48. In other words, the handle assembly 14 closes the open end of the utility track 48 when installed thereto.

Referring now to FIGS. 13, 14 and 15, a handle assembly 14′ in accordance with a second embodiment will now be explained. In view of the similarity between the first and second embodiments, the parts of the second embodiment that are identical to the parts of the first embodiment will be given the same reference numerals as the parts of the first embodiment. Moreover, the descriptions of the parts of the second embodiment that are identical to the parts of the first embodiment may be omitted for the sake of brevity. The parts of the second embodiment that differ from the parts of the first embodiment will be indicated with a single prime (′).

The handle assembly 14′ of the second embodiment is a modified version of the handle assembly 14 of the first embodiment. In the second embodiment, the handle assembly 14′ includes a base 60′ and grip handle 62′. The base 60′ is similar to the base 60 of the first embodiment, but with slight modifications. Specifically, the base 60′ includes an attachment portion 66′, a contoured portion 68′ and a handle supporting portion 70′. The attachment portion 66′ of the base 60′ is narrowed, as compared to the base 60 of the first embodiment. Further, the contoured portion 68′ is also narrower that the contoured portion 68 of the first embodiment. Finally, the handle supporting portion 70′ is smaller and narrower than the handle supporting portion 70 of the first embodiment such that the grip handle 62′ is significantly longer than the grip handle 62 of the first embodiment. Also, the attachment portion 66′ includes a projection 66 c′ that is inclined such that the projection 66 c′ contacts a greater surface area of the attachment assembly 64 (identical to that described in the first embodiment) thereby preventing pivoting or rotation of the base 60′ relative to the attachment assembly 64 and the utility track 48.

With the handle assembly 14′ installed to the utility track 48, the grip handle 62′ is positioned such that with the tailgate 26 in the open orientation, an individual using the step 30 to enter the cargo area 18 grabs the grip handle 62′ for assistance in stepping up into the cargo area 18 and/or stepping on to the tailgate 26.

Third Embodiment

Referring now to FIGS. 16 and 17, a handle assembly 14″ in accordance with a third embodiment will now be explained. In view of the similarity between the first, second and third embodiments, the parts of the third embodiment that are identical to the parts of the first and/or second embodiments will be given the same reference numerals as the parts of the first and/or embodiments. Moreover, the descriptions of the parts of the third embodiment that are identical to the parts of the first and/or embodiments may be omitted for the sake of brevity. The parts of the third embodiment that differ from the parts of the first and/or second embodiments will be indicated with a single prime (′) or a double prime (″).

In the third embodiment, the first side wall 22 is as described with respect to the first embodiment. In the third embodiment, the utility track 48 has been removed. Therefore, the inner panel 42 defines an upright surface 48′. Further, the handle assembly 14″ of the third embodiment fastens directly to the inner panel 42 of the first side wall 22 via the fasteners F₁ overlaying a portion of the upright surface 48′ of the first side wall 22.

The handle assembly 14″ of the third embodiment is a modified version of the handle assembly 14′ of the second embodiment. In the third embodiment, the handle assembly 14′ includes a base 60″ and the grip handle 62′ of the second embodiment. The base 60″ is similar to the base 60′ of the second embodiment, but with slight modifications. Specifically, the base 60″ includes an attachment portion 66″, a contoured portion 68″ and a handle supporting portion 70″. The attachment portion 66″ of the base 60′ is narrowed, as compared to the base 60 of the first embodiment. Further, the contoured portion 68″ extends from an upper end of the attachment portion 66″, extends inboard from the attachment portion 66″ and defines a 90-degree angle therebetween. The contoured portion 68″ is also somewhat elongated. Specifically, the contoured portion 68″ is dimensioned to position the grip handle 62′ such that the grip handle 62′ is spaced apart from the first side wall 22. A distal end of the contoured portion 68″ defines the handle supporting portion 70″. The grip handle 62′ is welded or otherwise rigidly fixed to the handle supporting portion 70″ and is significantly longer than the grip handle 62 of the first embodiment. Since there are two fasteners F₁ attaching the handle assembly 14″ to the first side wall 22, the grip handle 62′ cannot pivot or rotate relative to the first side wall 22.

With the handle assembly 14″ installed to the upright surface 48′ of the first side wall 22, the grip handle 62′ is positioned such that with the tailgate 26 in the open orientation, an individual using the step 30 to enter the cargo area 18 grabs the grip handle 62′ for assistance in stepping up into the cargo area 18 and/or stepping on to the tailgate 26.
